The Independent Police Complaints Commission (IPCC) is probing the death of a 37-year-old who was stopped by police in Agar Grove, Camden Town, last Thursday.

The man died in hospital three days later on Sunday.

According to police accounts, he became unwell while “being stopped” at about 11am.

Officers and paramedics administered first aid at the scene before he was taken to hospital.

The IPCC is appealing for any witnesses who saw the man’s contact with police.

A spokesman said: “Witnesses may have seen an Asian man, of average height and slim build, wearing a red top and dark trousers, on the cycle path at the junction of Agar Grove and Murray Street along with [Metropolitan Police Service] officers.”

IPCC investigators were sent to the scene after being contacted by police last Thursday.

IPCC Commissioner Jennifer Izekor said: “This is a tragic incident in which a 37-year-old man has died.

“The IPCC will carry out a robust and thorough investigation into the circumstances and nature of his contact with the police, the events leading up to his becoming unwell, his hospitalization and subsequent death.

“My thoughts and sympathy are with his family at what must be an incredibly difficult time.

“I would urge anyone with any information about this incident or anyone who witnessed any part of the police contact with the man to come forward to the IPCC as soon as possible.”

The IPCC witness appeal number is 0800 015 4876 or people can email agargrove@ipcc.gsi.gov.uk.
